A business service selection model for automated web service discovery requirements
Automated web service (WS) discovery, i.e. discovery without human intervention, is a goal of service-oriented computing. So far it is an elusive goal. The weaknesses of UDDI and other partial solutions have been extensively discussed, but little has been articulated concerning the totality of requirements for automated web service discovery. Our work has led to the conclusion that solving automated web service discovery will not be found through solely technical thinking. We argue that the business motivation for web services must be given prominence and so have looked to processes in business for the identification, assessment and selection of business services in order to assess comprehensively the requirements for web service discovery and selection. The paper uses a generic business service selection model as a guide to analyze a comprehensive set of requirements for facilities to support automated web service discovery. The paper presents an overview of recent work on aspects of WS discovery, proposes a business service selection model, considers a range of technical issues against the business model, articulates a full set of requirements, and concludes with comments on a system to support them
Participative social work and urban change: two case studies in Lisbon and Bucharest
Focusing on two initiatives working within disadvantaged urban neighborhoods in Bucharest and Lisbon, we want to discuss the civil society’s capacity to adapt to the changing social opportunities and difficul-ties, and its ability to create equal access to resources and opportunities. We propose to compare some aspects of both initiatives in these two historical and socio-political Southern European urban contexts, trying to better understand these processes: what they manage to do; what they find hard to do; who helps them; their relationships with different state structures (municipality, schools, national agencies etc.); their relationships with different people in the area of work; their future perspective, and so on. Our diverse social activist and academic background in anthropological, sociological, geographical fields allows us to a deeper understanding of the strengths and limits of theoretical and practical dimensions of social research process, witch we would like to discuss, also
Vortex and gap generation in gauge models of graphene
Effective quantum field theoretical continuum models for graphene are
investigated. The models include a complex scalar field and a vector gauge
field. Different gauge theories are considered and their gap patterns for the
scalar, vector, and fermion excitations are investigated. Different gauge
groups lead to different relations between the gaps, which can be used to
experimentally distinguish the gauge theories. In this class of models the
fermionic gap is a dynamic quantity. The finite-energy vortex solutions of the
gauge models have the flux of the "magnetic field" quantized, making the
Bohm-Aharonov effect active even when external electromagnetic fields are
absent. The flux comes proportional to the scalar field angular momentum
quantum number. The zero modes of the Dirac equation show that the gauge models
considered here are compatible with fractionalization
Beyond Polycystic Kidney Disease
Tuberous sclerosis(TS) is an autosomal dominant disease caused by mutations in TSC1 and TSC2 genes. TSC2 gene is located in chromosome 16p13.3, adjacent to PKD1 gene, responsible for the autosomal dominant polycystic kidney disease. In a rare subgroup of patients, the presence of a deletion which simultaneously affects the TSC2 and PKD1 genes has been confirmed. TSC2/PKD1-Contiguous Gene Syndrome is characterised by the early appearance of autosomal dominant polycystic kidney disease in combination with several phenotypic manifestations of TS. We present a 13-year-old girl with bilateral renal cysts detected at the age of 9 months. At the age of 13, she was referred to the Dermatology Outpatients Clinic due to a facial cutaneous eruption. She presented with facial erythema, fibroadenomas with malar distribution and disseminated hypomelanotic macules, meeting the criteria for TS. TSC2/PKD1 Contiguous Gene Syndrome deletion was suspected, being later confirmed by genetic testing.info:eu-repo/semantics/publishedVersio

Relação entre o equilÃbrio e o medo de cair em idosos
O equilÃbrio corporal constitui uma das funções mais importantes do organismo, estando por isso diretamente associado à qualidade de vida do indivÃduo. Algumas das alterações decorrentes do processo de envelhecimento, nomeadamente a nÃvel músculo-esquelético, neuromuscular e sensorial, influenciam a mobilidade funcional e a capacidade para manter a estabilidade em indivÃduos idosos1. As manifestações de desequilÃbrio levam a uma maior predisposição para quedas e suas consequências diretas como fraturas, imobilidade e medo de cair, levando a uma redução da autonomia pessoal e social e a uma limitação das atividades da vida diária (AVD’s), interferindo na qualidade de vida e podendo, nalguns casos, conduzir à morte
